CBS is moving aggressively to shake up its 2010-11 season, canceling "Cold Case," ''Ghost Whisperer" and five other series.

According to a person familiar with the changes, other canceled shows include "Numb3rs," ''The New Adventures of Old Christine," ''Gary Unmarried," ''Miami Medical" and "Accidentally on Purpose." The person, who wasn't authorized to discuss the changes publicly, spoke on condition of anonymity.

The wholesale axings came as a surprise, given the respectable ratings earned by some of the shows and CBS' standing as the most-watched network.

The cancellations will clear shelf space for newcomers, including William Shatner's first sitcom, a police drama with Tom Selleck and other shows tobe officially announced Wednesday by CBS.
